Title: Fluid heater with improved heating elements controller
Inventor: SEITZ DAVID
IPC: H05B1/02
Filed: 1996-09-06
Abstract: An electrically powered water heater (10) includes a plurality of heating elements (22, 34, 44 and 50) for substantially instantaneous heating of fluid passing through the heater. A controller for powering the plurality of heating elements is responsive to a temperature sensor (30) in fluid communication with the heated fluid. The temperature sensor activates each of the plurality of heating elements for a predetermined period of time that is preferably no more than 32 half cycles. The controller activates a second heating element (34) after a delay of preferably no more than 8 half cycles after activating a first heating element (22). The predetermined period of time for activating each of the plurality of heating elements may be substantially equal, such that each heating element contributes substantially equally to the heating of fluid. In one embodiment, the heater housing is provided with a plurality of chambers (9), and a heating element is provided within each of the plurality of chambers.

Inventor: WALKER RICHARD E
IPC: F42B3/14
Filed: 1998-04-24
Abstract: Exothermic reaction mixtures are electrically ignited with a low cost foil strip of two conductive strips separated by a layer of insulation. One or more holes are formed in the ignitor to create shaped spark plasma on one side and a venting plasma on the opposite side of the hole. The spark with low energy requirements is sufficient to ignite exothermic reactions for welding, casting and other uses. The ignitor may be part of reusable crucibles and molds, or expendable packages, containers, and molds, or smaller squibs for igniting larger charges. The ignitor may be immersed in or substantially adjacent the charge of exothermic material. The spark forming hole or holes is made and shaped by a punch in a simple and low cost manner. The ignitor eliminates the need for starting powders or materials and flint gun ignitors.

Title: Method of determining the hepatic status of an individual, including a liver transplant recipient
Inventor: MANNING FIONA MARY
IPC: G01N33/573
Filed: 1996-02-02
Abstract: A method of determining the hepatic status of a subject comprises measuring the level of the pi glutathione S-transferase (.pi.GST) isoform in a sample of a biological fluid from the subject by an immunoassay specific for the .pi.GST  isoform, comparing the level of .pi.GST measured with the normal range of .pi.GST in the biological fluid and, when an increase in .pi.GST level relative to the normal range is detected, determining the hepatic status of the subject based on the level of .pi.GST in the biological fluid. The method has particular application in the case of liver transplantation enabling one to determine at a very early stage post-transplantation a likelihood of rejection because the primary graft rejection generally occurs in the biliary tree.

Filed: 1997-07-31
Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Zeigler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50 %, an Mw/Mn below 3, and an Mz/Mw below 2. The films may be used advantageously in composite structures with fabrics (either woven or non-woven) to fabricate such articles as house-wrap.
